WORD-REGISTER FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Apr. 18, .191 1..

Application filed July 31, 1907, Serial No. 386,341. Renewed March 11,1911. Serial No. 613,912.

To alt w/im/i it may concern Be it known that I, SAMUEL 1..l.\'i"ri-:uson, of .Brookline, county of Norfolk, State ofMassachusetts, have invented an improvement in \Vord-Registers forTvpc-lVi-iters, of which the following description, in connection withthe accompanying drawings, is a. specification, like characters on thedrawings representing like parts.

This invention relates to certain improvements in means forautomatically recording the number of words written upon a type writingmachine, and has for its object to provide an automatic mechanism which,in the ordinary use of the machine, will only register .after a word hasbeen written. I accomplish this object by the means shown in theaccompanying drawing, in which,

Figure 1 is a plan view of the typewriting machine provided in myinvention. Fig. 2 is a cross section on the line 22 of Fig. 1. Fig. 3 isa section on the line 3-3 of F ig. 1.

The typewriting machine in connection with which my invention isemployed is similar to the machines in general use, and only such partsof the machine as cooperate with my improvements are shown in thedrawing.

In the drawing a indicates the frame of the machine, Z) the space-bar,which is adapted to be depressed to move the carriage in the ordinarymanner, and c the key-levers which are also adapted to be depressed tooperate the type-bars in the ordinary manner.

According to my invention I provide a lever cl which is pivoted at cl tothe front side of the frame of the machine, said lever having a toeportion (Z which is adapted to extend beneath the space-bar and engagethe under side thereof when the lever is in its normal position. Saidlever is also provided with an arm at at the opposite end thereof fromthe toe which extends upwardly and horizontally over one side of themachine, said arm being adapted to engage the vertically movableoperating arm 6 of a register 6, of suitable form, which is mounted onthe side frame of the machine. An arm d is also provided on lever (Zwhich extends transversely thereof from the point at which its pivot dis located, and a spring 7 is connected at one end to a pin f, locatedin the upper end of said arm at, and at its other end to a pin 9 mountedin the frame of the machine, said pin 1 being so located that when thelever rt is'in its normal position with the end (F thereof hearingagainst the under side of the space-bar, as in the full line position ofFig. 3, the center .of the pivot (1 will be either in, or slightly tothe right of the straight line between pins and 5/, so that said spring7 will act in a line which either intersects the center of the pivot (Z,or lies at the opposite side of said center from the toe end \Vhen thespace bar is depressed the pivot. will be swung to one side. so that thespring will act in a line which is at the side of the center of thepivot- (Z', next the end (Z of the lever (Z, thus acting to hold thelever in the depressed position indicated in dotted lines in Fig. 2. Itfollows, therefore, that when the lever is depressed by the space-bar,it will not automatically return with the latter, but will be held insaid depressed position until moved therefrom.

A bar i is provided which extends beneath all. of the key-bars c, saidbar 2' being provided with arms 2'. which are pivoted at at oppositesides of the machine. The lever (Z is provided with an arm (Z whichextends beneath one of the arms i, so that the latte always rests onsaid arm (Z as shown in full lilies in Fig. 3.

The operation is as follows: hen the space-bar Z) is depressed to movethe carriage a space, the lever will be moved down to the dottedposition of Fig. 2, causing its arm 653 to lift the register arm 6 tooperate the register. The arm d of said lever will also be lifted,causing it to swing up arms z" and lift the bar 2' into engagement withthe under edges of the key-bars 0. As before stated, the lever (Z willremain in the depressed position when the space-bar is again lifted, sothat the spaeebar may then be operated indefinitely without furtheroperating the register. However, when any one of the key-bars aredepressed to operate a type-arm, said cross-bar i will be depressed,swinging the arm 2" thereof downwardly, thus causing the arm 03 to bedepressed and causing the opposite end of lever d to be swung upwardly,so that the toe d thereof again engages the under side of the spacebar.The parts are thus returned to the full line position of Fig. 2, so thatthe next time the space-bar is depressed the register will again beoperated. It Will, therefore, be apparent that, with the above describeddevice, a Word or character will not be registered until it has beenwritten and the carriage has been moved a space, and that nothing willbe registered it the carriage is moved more than one space Without againstriking a key to Write another Word or character.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is 1. In a typewriting machine, the combinationwith the space-bar thereof, of a register, a fulcrumed lever having onearm in normal engagement with said space-bar and an opposite arm inengagement with the operating-arm of the register, means for normallyholding the arm engaging the spacebar in depressed position, a pivotedcross-bar situated beneath the key-levers and means carried by thefulcrumed lever, whereby said lever may be returned to normal positionwhen the cross-bar is depressed.

2. In a typeWriting machine, the combination with the space-bar thereof,of a register, a fulcrumed lever having an arm engaging the space-barand an opposite arm engaging the operating-arm of the register, a springarranged to temporarily hold the first mentioned arm in depressedposition, a pivoted cross-bar situated below the key-levers, and an armcarried by the tulcrumed lever, adapted to be operated upon by the crossbar to return the said lever to normal position.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.
